CHECK-ROWER FOR CORN-PLANTERS SPECIFICATION forming part of LettersPatent No. 280,641, dated July 3, 1883.

Application filed April 14, 1883. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES S. LocKE, a citizen of the United States ofAmerica, residing at J oliet, in the county of VWill and State ofIllinois, have invented certain new and useful Improvements inOheck-Rowersfor Corn- Planters, of which the following is aspecification, reference being had therein to the accompanying drawings.

Myinvention relates to an attachment for that class of corn-planters inwhich the slide for the seed-boxes is operated by a cable fastened ateach end of the field and having knots at regular intervals engagingwith a vibratable member of v the planters attachment, by whichreciprocating motion is transmitted to the seed-box slide; and itconsists of the novel devices and combinations of devices, hereinafter'described and specifically claimed.

In the accompanying drawings, Figure 1 represents a plan view of thecheck-row attachment; Fig. 2, a longitudinal vertical section throughthe center of the same; Fig. 3, an edge view of the attachment; and Fig.4, a longitudinal section of the connecting-bar.

Corresponding letters in the several figures of the drawings designatelike parts.

A denotes the main or bottom plate of the frame of the attachment,consisting of a seg mental plate, a, that upon its radial ends hasprojecting strips 7) and c, to one end a project ing arm, (I, and iscast solid with a central bar, 0, which to one end has lugs y, and toits opposite end a pulley, f, and stud for guiding the knotted cable B.V Upon strip 1) is fitted the strip h of another segmental plate, 0, andis secured thereon by two dowels, t, of strip h, fittinginto sockets ofstrip b, and by a screw, that is tapped into strip 1).

The plates A and C have each a hub, Z, that is concentric with the curveof their segments, and into each of such hubs Z is pivotally secured thetrunnion Z of a Y-shaped lever D or D, by means of a washer, m, securedupon the end of such trunnion by a screw, n. The strips 1) and h holdthe plates A and O the proper distance apart for the Y-shaped levers D Dto be separated just far enough for the cable B to pass freely between,but to exclude the D are chamfered, and their trunnions Z are aboutone-third of the entire length of such levers distant from that forwardend, and are arranged to be central to the line on which the knottedcable B is guided through the attachment.

To near its pointed end each lever D D has formed a trunnion, p, toengage with the eyes of the bifurcated end of connecting-bar E, that ismade in two halves secured together by dowels and a bolt, g. This bar E,holds the two levers D D in line with each other, and itsoppositebifurcated and eyed end is coupled with either of a series of trunnions,1', that project from the sides of the end of a lever, F. This lever Fis pivoted upon arm d of plate A by a fulcrum-bolt, s, and its rear endhas a series of holes for pivotally coupling a bar or rod at thenecessary distance from the fulcrum of such lever, according to thelength of stroke desirable for the seed-slide lever.

At about half distance between trunnion Z and the rear end of lever Dsuch lever D is provided with a boss for pivotally securing by a screw,2, a small roller, u. A latch, G, is pivoted with one end on a screw,1), tapped into the end of plate 0. This latch, by a leaf-spring, H, isdepressed to bear upon roller u, and has inclined edges, that tend tolock the levers D D, on either end of their stroke, with sufficientresistance to require a certain amount of side pressure before suchlevers can be started toward the opposite end of their stroke.

Projecting and flaring guard-lugs w are formed to the corners of therear ends of levers D D, that will prevent the knotted cable fromleaving its prescribed course.

The plate A of this check-rower attachment is secured in proper positionupon the middle or either side of the corn-planter frame by bolts passedthrough holes in strip 0 and through arm (I, or in another convenientmanner, and the lever F is to be suitably connected by a rod or bar withthe lever or .levers that operate the seed-box slides.

The knotted cable B, after being anchored to the field, can be readilyinserted from the side of strip 0 between the levers D D, and thenplaced between pulley f and stud g at one end of plate A,'and betweenguide-lugs 1 of knot-s 0 that are formed or secured upon such 1 theother end of plate A, when, as the machine cable. The pointed forwardends of levers D l is being moved over the field in the directionindicated by the arrows, a knot, 0, of such stationary cable will. comein contact with the edges of levers I) D, and while the cable itself hasa free passage through the space between such levers, the knot will haveto followthe relativcly'angular lines of these levers, thereby creatinga side pressure that will overcome the resistance of spring-latch (l,and will vibrate the levers l) l) to swing to the opposite end of theirstroke, alter which movement the knot 0 will have a free passage between guard-lugs w and guide-lugs 3 The levers D I) thus having attainedtheir opposite position, the next knot 0 of cable 1 will. now be guidedto come in contact with the edges of the opposite side of levers D l),which will tend to swing the levers backto their iirst position, and inthis manner successive knots will come in contact alternately with theopposite edges of levers l) l), and will vibrate these levers to and frowithintermittent quick strokes. The vibrations of levees l) Dbeingin'iparted to lever F byconnecting-barE, such lever F again, by anysuitable connection, is to be coupled with the lever or armthat operatesthe seed-box valves or slides in a manner that each movement ol thelevers D I) will tend to drop a seed.

Vith the above device the seed-box slide or valve is thus operated by aquick short stroke. so essential in the correct dro )ping of corn.

The movements of the attachment are very easy and yet positive. I tsconstruction is very simple and inexpensive, and it has no parts thatcan readily wear out or break, and when accidentally broken can beeasily replaced 1 a duplicate piece.

These cheek'rower attachments can be applied to all. styles ofcorn-planters, and can be made right and left, to be secured to eitherone or both sides of the machine.

I am aware that a cam composed of two parts, between which the check-rowcable passes, and the knots adapted to act on the edges of such cam in.alternate order to vibrate the same, is old, and such I do not desire toclaim; but

\Vhat I claim is 1. In a check-rowel. i'or corn-planters, the Y-shapedlevers 1') I), each pivoted independ ently and axially in line with theother, and each having cxteriorly to its forward end a trunnion, p, andboth levers being coupled to work in conjunction by and to onebifurcated which connects with lever F, that again is to connect withthe seed-box slides, all substantially as and for the purpose set forth.

2. Theherein-described check-rowerior cornplanters, consisting ofbase-plate A, having cable-guides and cap-plate (J, the Y-shaped leversl.) l), pivoted between such plates, each independent of and axially inline with the other, and with an open space between, such levers l) 1)having each a trunnion, p, to couple with one end of bar 1*], thatconnects with lever F, and lever I), having a stud or roller, 'u,engaging with pawl G, thatis pivoted to cap-plate C and is depressed byspring H, the whole being constructed and arranged, substantially as(hscribed, to operate as specified.

In testimony whereof I at'lix my sigimture in presence of two witnesses.
